| 摘 要： | 在水溶液电解质中,以活性炭纤维(ACF)为电极,采用微孔曝气方式,吸附-电催化氧化两步联动降解非水溶性气态VOCs。以苯为研究对象,正交实验和单因素分析实验结合,正交实验确立最佳实验条件为:鼓气速率80L/h、苯/乙醇(体积)=30/150、电压10V、电解质浓度2g/L;最佳实验条件下,气相中苯的去除率为93.3%。单因素分析实验考虑了鼓气速率、苯浓度、电解电压、电解质浓度等因素的变化对去除率的影响。

| Abstract: | This paper presents a bench-scale experiment on degrading volatile organic exhaust gas (benzene as an example) by using setups made of activated carbon fiber (ACF) electrodes and a micro-aeration system.Optimum parameters are determined by orthogonal test and single-factor effect analysis with respect to aeration rate,volume ratio of benzene/ethanol (representing benzene concentration),voltage and electrolyte concentration.The research result indicates that under the optimal condition,removal of gaseous ben... |
